"As part of my effort to help these children and caregivers, I challenge the entire community to get behind this cause and help match my gift by raising an additional $2 million to support all of these brave and inspiring children," she continues, challenging the community to partner in monetarily matching her donation as part of the Heart Center Challenge.

The Jennifer Lawrence Foundation Cardiac Intensive Care Unit (CICU) and a renovation of the existing “Just for Kids” Critical Care Center are anticipated to cost nearly $25 million. When completed, the CICU "will feature private rooms dedicated to children recovering from heart procedures, open heart surgery including heart transplant, heart failure and other conditions requiring intensive care" in the 14-bed unit that "will offer space for families to stay with their children," according to a press release from Children's Hospital Foundation.

The hospital's heart center is the only pediatric cardiovascular program in Kentucky, where more than 5,000 children visit each year and more than 17,500 procedures are performed annually.

Late last year, the Oscar-winner made a surprise visit to the hospital in an effort to spread Christmas cheer to patients and staff.
